無法針對Laravel中的多個模型進行身份驗證

Question

我正在嘗試為我的應用程序中的超級管理員和用戶（單獨的表）設置身份驗證，但是它的行為不符合預期。 對User模型的身份驗證可以正常工作，但對Superadmin模型則不能。 我的模型如下：

User.php：

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'username', 'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
}

Superadmin.php：

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class Superadmin extends Authenticatable
{
    use Notifiable;

    protected $guard = 'superadmin';

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'username', 'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];
}

我的config / auth.php

<?php

return [

    'defaults' => [
        'guard' => 'web',
        'passwords' => 'users',
    ],

    'guards' => [
        'web' => [
            'driver' => 'session',
            'provider' => 'users',
        ],
        'api' => [
            'driver' => 'token',
            'provider' => 'users',
        ],
        'superadmin' => [
            'driver' => 'session',
            'provider' => 'superadmins',
        ],
        'superadmin-api' => [
            'driver' => 'token',
            'provider' => 'superadmins'
        ],
    ],

    'providers' => [
        'users' => [
            'driver' => 'eloquent',
            'model' => App\User::class,
        ],
        'superadmins' => [
            'driver' => 'eloquent',
            'model' => App\Superadmin::class,
        ],
    ],

    'passwords' => [
        'users' => [
            'provider' => 'users',
            'table' => 'password_resets',
            'expire' => 60,
        ],
        'superadmins' => [
            'provider' => 'superadmins',
            'table' => 'password_resets',
            'expire' => 15,
        ],
    ],

];

對我來說似乎正確，但顯然不正確，因為在為超級管理員用戶輸入正確的憑據后發生以下情況：

為普通用戶輸入憑據可以正常工作：

如果你走的話

vendor\\laravel\\framework\\src\\Illuminate\\Foundation\\Auth\\AuthenticatesUsers.php

您將看到一個名為attemptLogin的方法

其中有

/**
 * Attempt to log the user into the application.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return bool
 */
protected function attemptLogin(Request $request)
{
    return $this->guard()->attempt(
        $this->credentials($request), $request->filled('remember')
    );
}

現在，如果您使用guard方法，它將使用

/**
 * Get the guard to be used during authentication.
 *
 * @return \Illuminate\Contracts\Auth\StatefulGuard
 */
protected function guard()
{
    return Auth::guard();
}

現在，如果您進一步研究

vendor\\laravel\\framework\\src\\Illuminate\\Auth\\AuthManager.php您將看到“后衛方法”期望使用$name

/**
 * Attempt to get the guard from the local cache.
 *
 * @param  string  $name
 * @return \Illuminate\Contracts\Auth\Guard|\Illuminate\Contracts\Auth\StatefulGuard
 */
public function guard($name = null)
{
    $name = $name ?: $this->getDefaultDriver();

    return $this->guards[$name] ?? $this->guards[$name] = $this->resolve($name);
}

現在，查看getDefaultDriver方法，該方法從auth配置文件獲取默認值：

/**
 * Get the default authentication driver name.
 *
 * @return string
 */
public function getDefaultDriver()
{
    return $this->app['config']['auth.defaults.guard'];
}

在您的auth.php中添加：

'login' => [
    'guard' => [
        'web',
    ]
],

因此，在您的logincontroller.php ，您可以覆蓋Guard方法以使用特定的Guard：

<?php

namespace App\Http\Controllers\Auth;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use App\Modules\Core\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;

class LoginController extends Controller
{
    /*
    |--------------------------------------------------------------------------
    | Login Controller
    |--------------------------------------------------------------------------
    |
    | This controller handles authenticating users for the application and
    | redirecting them to your home screen. The controller uses a trait
    | to conveniently provide its functionality to your applications.
    |
    */

    use AuthenticatesUsers;

    /**
     * Where to redirect users after login.
     *
     * @var string
     */
    protected $redirectTo = '/home';

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }


    /**
     * Attempt to log the user into the application.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return bool
     */
    protected function attemptLogin(Request $request)
    {
        foreach(config('auth.login.guard') as $guard) {
            return $this->guard($guard)->attempt(
                $this->credentials($request), $request->filled('remember')
            );
        }

        return false;
    }

        /**
     * Send the response after the user was authenticated.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    protected function sendLoginResponse(Request $request)
    {
        $request->session()->regenerate();

        $this->clearLoginAttempts($request);

        foreach(config('auth.login.guard') as $guard) {
            return $this->authenticated($request, $this->guard()->user())
                    ?: redirect()->intended($this->redirectPath());
        }

        return false;
    }

        /**
     * Log the user out of the application.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function logout(Request $request)
    {
        foreach(config('auth.login.guard') as $guard) {
            $this->guard($guard)->logout();
        }

        $request->session()->invalidate();

        return redirect('/');
    }

    /**
     * Get the guard to be used during authentication.
     *
     * @return \Illuminate\Contracts\Auth\StatefulGuard
     */
    protected function guard($name = null)
    {
        return Auth::guard($name);
    }

}
